Big Dog is the huge quadrupedal robot that stomped its way into our hearts a few years ago with its wild gait and hydraulic whine. Now, however, there’s a new Dog in the mix, the StarlETH, a smaller robot made at ETH Zurich. This guy may be tiny but he’s uniquely suited to running through and over obstacles and in environments that Big Dog may not be able to tackle.

This wee robot can right itself if it falls and runs at 1.5 mph. It also handles obstacles a bit better than Big Dog and has improved hip movement. You can see it fall below – it has active and passive damping so it can either right itself in one motion or bounce around a bit to fix its gait.

Starl stands for Series Compliant Robotic Leg and is designed to handle multiple terrains and environments. It’s a bit small right now but scaling this monster up should give Big Dog a run for its money.
